Hello developers,

running a python (__run__.py) script 
from  within a jar archive with:

  jython -jar prog.jar

fails if prog.jar is located outside
the working folder AND the path 
contains special characters AND 
__run__.py contains code like the
testcase above:

Here is a simple testcase:

# __run__.py  begin --
from java.lang import Thread
class PythonThread(Thread): pass
# __run__.py   end  -- 

Calling:

  jython -jar folder/prog.jar

will work, whereas

  jython -jar folder-2/prog.jar

fails with:

Exception in thread "main" Traceback (innermost last):
  File "__run__", line 8, in ?
